I don't believe you will actually play college games....they will probably fast forward to when you graduate or what not and then you will see your attributes after that. If I am wrong somebody correct me.
yes if you assigned to the minors....you play all the minor league games your in.
If your a Pitcher....you can decide of course will be be a SP or a RP or even a CP. I have dabbled playing a pitcher and first off....it's awesome. And if your a starter....you will probably start in the minors and yes start games. If your a RP or CP you will come out of the bullpen.
